If you support their philosophy and vote, as you say, "often" for them, you support the party.
I find that those claiming to be pro choice when it comes to abortion oppose choice, freedom and liberty on issues such as school CHOICE, whether or not someone has to buy healthcare as with the Obamacare mandate, and being given the CHOICE of whether or not to financially support through social welfare programs those that make life choices they can't afford to pay for themselves.
If you're pro choice only with things like abortion, you're pro abortion.
